Definition: Given a simple high-school level math question, you are required to solve it and provide the final answer. The final answer is always a single number. These questions can range from a variety of topics like simple arithmetic, solving equations, converting a quantity from one unit to another, finding remainders/GCD/LCM, finding probabilities etc. Each question has only one correct answer. This answer can be a positive or negative integer, a fraction or a decimal number. If the answer is a negative number use the hyphen (e.g. -42) symbol for the minus sign. For decimal numbers, do not add extra zeros after the decimal point. For fractional numbers, separate the numerator and denominator using a forward slash (e.g. 3/25).
Input: Let w be 94/18 + 4/(-18). Let i(j) = j**3 + j**2 - 4*j + 6. Let y be i(4). Let q be (1 + 1/(-2))*y. Solve -x - 10 = -0*x - 5*r, -4*x - w*r = -q for x.
